Ocean, Harbor and Bay Water Quality Report

Executive Summary The 2017 and 2018 Ocean, Harbor and Bay Water Quality Report provides updated data on sewage spills and their impacts resulting in ocean water closures and provides an analysis of bacteriological water quality data collected at Orange County’s ocean, harbor and bay waters. The Health Care Agency (HCA) Ocean Water Protection Program (OWPP) has been collecting information on sewage spill incidents in Orange County for a 32-year period (1987 – 2018) and this data is utilized to identify the main causes of sewages spills and reduce the number of ocean water closures in Orange County.

In addition, the OWPP has been collecting bacteriological water quality data for the 19-year period (2000 – 2018) that California Assembly Bill 411 (AB 411) Ocean Water-Contact Sports Standards has been in code. This data is used to present an overview of the year-to-year variability and longterm trends associated with ocean, harbor and bay water quality in Orange County.

Key findings from the Ocean, Harbor & Bay Water Quality Report

number of posted warnings dropped significantly to 37.6 BMDs a year. Low rainfall totals and less urban runoff impacting the beach areas in Orange County are considered to be the two major factors for the decrease in the number of BMDs.

The Ocean Water Monitoring Program As part of the Orange County Health Care Agency (HCA), the Environmental Health (EH) Ocean Water Protection Program (OWPP) is responsible for protecting the public from exposure to ocean and bay waters that may be contaminated with sewage or may cause illness along Orange County’s 42 miles of open ocean coastline and 70 miles of harbor and bay frontage. Ocean and bay waters used for recreational activities such as swimming, surfing and diving must meet specific bacteriological water quality standards to be considered safe for such purposes.

Sewage Waste Discharges Sewage waste discharges commonly known as “sewage spills,” occur when wastewater being transported via underground pipes overflows through a manhole, clean-out drain or broken pipe. Sewage spills can cause health hazards, damage homes and businesses, and threaten the environment, local waterways and beaches. Untreated sewage has high levels of disease-causing bacteria and viruses. Orange County OWPP is responsible for protecting public health by closing ocean, harbor and bay water areas affected by sewage spills.

Local and state agencies have legal jurisdiction and enforcement authority to ensure sewage spills are remediated. Allowing sewage to discharge from a home, business or public property may subject the responsible party to penalties and/or out-ofpocket costs to reimburse local and state agencies for cleanup efforts and for not reporting the sewage spill. As mandated by the California Health and Safety Code, any person who causes or permits a sewage discharge to any state waters must immediately notify the local health agency of the discharge. After a significant increase in the number of ocean water closures due to sewage spills in 1998, the OWPP started collecting detailed data on all sewage spills occurring in Orange County the following year (1999). Therefore, data on type of sewage waste discharges (e.g., private property owner, pipeline blockages and pipeline breaks) are only available from 1999 onward.

Ocean, Harbor and Bay Water Closures Due to Sewage Spills When a known release of sewage is reported to the OWPP, the ocean, harbor or bay water areas that may be affected by the sewage discharge are immediately closed to water-contact recreational activities. The closure area is based on many factors including type of sewage (e.g., untreated, secondary treated, etc.), volume of spill, location of spill, ocean currents and tides, historical sewage spills in the area and other pertinent information. After the initial closure area is established, the appropriate agencies are notified, the area is posted with closure signs, a press release is issued, the Ocean, Harbor and Bay Water Closure & Posting Telephone Hotline and Webpage are updated with the beach closure information, and daily bacterial sampling of the affected area is initiated.

The closed ocean or bay water area will be reopened or reduced in size when the contamination source has been eliminated and after two daily consecutive sampling results indicate the affected area meets the AB 411 Ocean Water-Contact Sports Standards.

The OWPP began recording information on ocean water closures in 1987. After a significant increase in the number of ocean water closures due to sewage spills in 1998, the OWPP started collecting detailed data on all sewage spills occurring in Orange County the following year (1999).

Ocean Water Postings Due To Bacteriological Standards Violations

and Bay Water Closure and Posting Hotline at (714) 433-6400, Webpage at www.ocbeachinfo.com and on Twitter http://twitter.com/ochealth.

Follow-up bacteriological water samples are collected at the posted location and the results are evaluated daily to determine if the posted warning area should be modified, kept the same or removed.

Upon implementation of the AB 411 Ocean Water-Contact Sports Standards in July of 1999, the OWPP began posting the required health warning signs at public beaches where the ocean, harbor or bay waters failed to meet state mandated recreational water quality standards.

To better protect the health of the residents and visitors to Orange County, OWPP collects bacteriological water samples at 142 ocean, harbor and bay locations throughout Orange County, year-round, even though regulations only require collection from April 1 through October 31. Sample results are reviewed daily by the OWPP to determine compliance with the seven AB 411 bacteriological standards established by the State of California. Each year the OWPP reviews the bacteriological water quality results for over 3,800 water samples collected from April 1 to October 31. Because ocean, harbor or bay water areas that violate the AB 411 Ocean Water-Contact Sports Standards may cause illness to recreational water users, the OWPP staff recommends staying out of the water at all beach areas that are posted with the health warning sign.

When a bacteriological water sample fails to meet an AB 411 Ocean Water-Contact Sports Standard, the following actions are taken: Warning signs are posted at the affected ocean, harbor or bay water area indicating that bacteria levels have exceeded health standards and ocean water contact may cause illness.

The information regarding the posted area is updated on the Ocean, Harbor

The detection and enumeration of disease-causing organisms (pathogens) identified with waterborne illness is difficult, time-consuming and costly. Thus, most water quality laboratories are required to test for fecal indicator bacteria (i.e., total coliforms, fecal coliforms and enterococci) as a means to ascertain the likelihood that human pathogens may be present in recreational waters. Fecal indicator bacteria normally occur in the intestines of all warm-blooded animals, are excreted in high numbers in feces, but can also be found in soil and decaying vegetation. Since there is no ideal indicator group, testing is done for more than one indicator. Total coliforms are a broad group of organisms that include fecal coliform bacteria as well as E. coli. The enterococci group has been determined to be a good indicator of water-contact associated gastroenteritis. The methods most commonly used to detect fecal indicator bacteria in

Appendix D Public Notification and Risk Communication Public notification and risk communication is a critical component of the OWPP. Public awareness and enhancing the capacity for informed personal choice are important factors in ensuring public health protections are provided to recreational water users. The OWPP has established and maintains an integrated management system to inform the public of the potential health risks associated with water contact activities in coastal recreational waters that do not meet applicable water quality standards. Multiple communication measures are promptly taken to notify the public when ocean, harbor or bay water areas do not meet or are expected not to meet AB 411 Ocean Water-Contact Sports Standards.

The OWPP implements the following types of public notification measures to communicate information regarding beach water quality and to protect the health of beach users: Beach Signs – Signs are posted to notify beach users of the current status of the ocean, harbor or bay water area. Posted beach signs are located where they are most likely to be noticed by beach users and provide a visual notice at the point of ocean water access.

Telephone Hotline – The Ocean, Harbor and Bay Water Closure & Posting Telephone Hotline has been established to inform the public about all beaches that are currently closed, posted with a health warning or when a rain advisory has been issued. The telephone hotline message is immediately updated when a change in the status of beach closures, postings or advisories occurs. The Ocean,

Webpage – The Ocean, Harbor and Bay Water Closure & Posting Web Page has been developed and is used to report beach closures, postings and rain advisories. The web page is updated immediately when the status of the closure, posting or advisory changes. The Ocean, Harbor and Bay Water Closure & Posting Web Page internet address is www.ocbeachinfo.com.

Social Media – Public notification of ocean water quality status changes are being communicated to the public through the social media network of Twitter. For the latest information and instant ocean water quality updates when they occur, follow us on Twitter at http://twitter.com/ochealth.

Press Releases – Public notification of a beach closure or rain advisory is provided in a press release issued by the HCA. The press release will indicate whether a closure or advisory is being issued, the reason for the closure or advisory, the area affected and the anticipated duration of the closure or advisory.

Annual Reports – To assess the health of the ocean, harbor and bay waters being monitored, the OWPP compiles a report of the beach closures, postings and advisories after the year has ended. The biennial Ocean, Harbor and Bay Water Quality Report provides an updated analysis of bacteriological water quality, describes year-to-year variability and trends for Orange County’s recreational waters, and includes data on sewage spills and beach closures. Reports from 2002 to present can be viewed and downloaded from the Ocean, Harbor and Bay Water Closure & Posting Web Page at www. ocbeachinfo.com.

Appendix F BMDs (BMD) The term “Beach Mile Days” is used to represent the measurement of the number of days and the linear area of ocean, harbor or bay front waters that are closed due to a sewage spill or posted for a violation of the AB 411 Ocean Water-Contact Sports Standards.

BMDs are calculated by multiplying the number of days of a closure or posting by the number of miles of beach closed or posted: (Number of Days) x (Miles of Beach Closed or Posted) = BMDs For example, if a sewage spill resulted in the closure of ½ mile of beach for 7 days, then: (7 days) x (0.5 miles of beach closed) = 3.5 BMDs of closure Another example, if 300 feet of beach is posted for a violation of the AB 411 Ocean Water-Contact Sports Standards for 5 consecutive days, then: (5 days) x (0.06 miles of beach posted) = 0.3 BMDs of posting Using BMD as a measurement of ocean and bay water availability is more meaningful than using the number of incidences or the number of days since BMD takes into account both the length of beach and number of days for a closure or posting. The State of California Water Resources Control Board and all California coastal counties use BMD for reporting closures and postings which provides a standardized measurement that allows comparison of different areas (beach to beach or county to county) and the assessment of closure and posting trends over time.
